Description:
Highland Heavy duty hydraulic motors features:
Highland Heavy duty hydraulic motors are an essential component of many industrial applications. Highland hydraulic motors are designed to convert hydraulic energy into mechanical energy, allowing machines to perform various tasks with great efficiency and power. They are commonly used in heavy machinery such as construction equipment, agricultural equipment, mining machinery, and material handling equipment.
Highland Heavy duty hydraulic motors come in a wide range of sizes, configurations, and power outputs. They can be classified into two main types: radial piston motors and axial piston motors. Radial piston motors are designed to handle high torque loads and are ideal for heavy duty applications, while axial piston motors are more efficient and are better suited for applications that require high speed and low torque.

Notices:
Hydraulic oil
The suitable replacement period for hydraulic oil in a sealed tank system is 2000 hours, and more often if the hydraulic oil is contaminated with water or other external materials or subjected to abnormal operating conditions.
As a general recommendation, the 10µ inlet oil filter should be replaced every spring or every 1500 hours (whichever occurs first) on a sealed tank system, or in an open tank system with an air filter fill cap. The oil filter should be replaced every 500 hours.
Heat Exchanger
The heat exchanger core and fins are kept clean at all times for maximum cooling and system efficiency, and the exterior of the heat exchanger is checked daily for blockages and cleaned as needed.
Application:
Mixer truck: concrete mixer truck, cement mixer truck;
Coal mining machinery: scraper;
Industry: pharmaceutical machinery;
Transport vehicles: road rollers, concrete pump trucks, stabilized soil mixers
HMF30 Factory Production & Inspection Evidence
Each HMF30-21 completes a recorded production and inspection step before it is released for shipment, with the unit photographed on the factory floor. The evidence is summarised below.
Factory Evidence
- Motor unit photographed on the production floor prior to packing
- Housing and shaft inspected visually ahead of shipment
- Ports and mounting interface verified against the HMF30 specification
- Final inspection performed to the product's technical requirements
Evidence Type: Factory Production / Visual Inspection
Application: Wheat harvester hydraulic drive
Product Status: Production / Pre-shipment Inspection
HMF30 Quality Control & Inspection
Each HMF30-21 motor goes through a set inspection route. Once assembled it is bench-run on the closed-loop motor stand, recording displacement, working pressure, speed, flow and torque, confirming overall and volumetric efficiency, and checking leakage; approval follows only when every value is within specification.
HMF30 Factory Performance Testing
Before delivery, every HMF30-21 passes a closed-loop bench test. Unit No. 02301060203001 was tested on 2023/1/6 13:51 at 36.5 ℃ at the 30 mL/rev rated displacement, 3800 r/min maximum speed and 38 MPa peak pressure (rated 35 MPa), with a power-recovery ratio of 10 %.
HMF30 Recorded Test Data
Recorded bench output for the HMF30-21 motor (component No. 02301060203001; 2023/1/6 13:51; 36.5 ℃; charge pressure 1.2 MPa):
| Speed n1 (r/min) | Pressure P2 (MPa) | Flow Q2 (L/min) | Displacement q2 (mL/rev) | Torque N1 (N·m) | Input Power P1 (kW) | Output Power P0 (kW) | Overall Eff. η (%) | Volumetric Eff. ηv (%) |

HMF30 Engineering Drawing
The HMF30-21 is covered by the HMF30/50 series motor drawing. Its output shaft is an involute spline of 21 teeth at a 16/32 radial pitch and a 30° pressure angle, with a dividing circle diameter of 33.34 mm. Four bolts with 3/8-16 UNC threads at 25 mm depth fix the SAE mounting flange. Leakage ports are L1 and L2; the speed-sensor installation port is 7/8-14 UNF-2B; and the flushing pressure measuring port and relief-valve taps are 9/16-18, 15 mm deep. Clockwise and counter-clockwise rotation are both available.

HMF30 Application / Project Evidence
The HMF30-21 closed axial piston motor was manufactured for a Saudi Arabian concrete mixer truck project. The order — logged internally as “Variable Piston Pump for Saudi Arabia” — came to 20 units, delivered to a Saudi Arabia-based customer and made by Shandong Highland Hydraulic Seiko Co., Ltd. On this product the motor drives the wheat harvester hydraulic drive within the closed-circuit hydrostatic transmission. The facts below are taken from that delivery's project records.
